Product Overview

Bundled Service deployment is a snap thanks to the ICX-250 from ADC Telecommunications.

ADCs’ ICX-250 allows cost-effective and quick deployment of analog voice and data services on a

single T1 access trunk.

The ICX-250 sports a sleek, low profile chassis and is configured via DIP switches, eliminating the

need for PC based craft interface and specialized training. LEDs are provided for monitoring the

status of ICX-250 under normal operation as well as under test conditions. Maintenance and

diagnostics are further enhanced via loopbacks and test patterns, all configurable from the DIP

switches. Additionally, network loopbacks can be used to test from a remote office.

ICX-250 addresses access needs for sites requiring economical adaptation of FXS analog voice

based key systems and PBXs to T1 services. ICX-250 supports TR-08 as well as ESF and D4

framing. Additionally, ICX-250 provides two high speed EIA530A/V.35 ports for insertion of

Routers or other data traffic in bundled service arrangements. For sites needing up to 24 analog

lines, with or without data requirements, ADC’s ICX-250 is an ideal solution.

The ICX-250’s primary function is to allow for remote termination of lines from a centrally-

located switch. Data ports are also provided on the unit for those applications where high speed

data deployment would be required.

The ICX-250 product is complimentary to the leading ICX-500 and Integrated Communications

Access server (ICX).

The ICX-250 from ADC Telecommunications - never before have bundled services been so

economical and easy to install and maintain.

mounting options are available.

• Simplified Maintenance - manual test DIP switches, maintenance test and LED

status indicators, all simplify maintenance operations.

4 Welcome Product Overview

ADCP-62-023 Issue 1, September 1998

TR-08

The TR-TSY-000008 Bellcore

TM

standard (commonly referred to as TR-08) describes the generic

requirements for interfacing between local digital switches and remote digital terminals via the

SLC 96

TM

digital loop carrier system.

TR-08 has three operational modes (ICX-250 supports mode I):

• Modes I & III are non-concentrated and provide unique mapping between channel

numbers and DS1 time slots.

• Mode II is concentrated and there are no pre-determined relationships between the

channels and timeslots. This allocation of channels to time slots is made possible by the

exchange of messages between the Local Digital Switch (LDS) and remote terminal (RT).

Although commonly referred to as the TR-08 standard, the RT channel numbering scheme supported

by the ICX-250 unit is described in section 9.9 of the Bellcore publication TR-TSY-000057.

The ICX-250 provides SLC-96 Frame Format and Data Link.

When a T1 port is configured for TR-08 format, the voice channels assigned to this port are identified

by “channel number” (according to the TR-TSY-000008 document), which may be different from

the T1 time slot number. The ICX-250 supports only Group A. The relation between a channel number

and corresponding slot number for TR-08 is shown in the following table.

Wall Mounting

Prior to wall mounting check to see if the environment is stable and free

from any extreme temperatures, humidity or vibrations of any sort. The

unit should be mounted with the fan to the top with at least 2 inches of

clear space on the sides, above, and below for adequate air flow. Allow at

least 6 inches for cable clearance and access to switches.

When attaching unit(s) to a wall make sure that appropriate fasteners such

as masonry anchors, heavy duty wood screws or expansion bolts are used

for heavy objects.

!!ATTENTION!!

Set all options prior to installing

mounting brackets, top cover cannot be removed

once brackets are in place.

Note:

Additional support hardware may be necessary

(not included with unit) to secure the unit properly to

the wall. If the surface is not solid enough to hold the

unit and attached cabling, it is recommended that a

small piece of 3/4” plywood be fastened to the wall before

attaching the unit. This will help ensure a more stable environment
